Meyendorff Castle or Meindorf Castle (Мeйендорф or Мeйндорф) is a Châteauesque architectural extravaganza constructed at the turn of the 20th century to Pyotr Boytsov's designs as a private residence of the Swedish-Baltic German , (a cadet line of the Baltic German noble house of Uexküll). Located between Barvikha and Odintsovo along Podushkinskoye Highway () in Odintsovsky District, Moscow Oblast west of Moscow, the castle was constructed between 1874 to 1885.
